“…The large H C and H IRR values of the FeCo ref sample are an indication of the presence of internal residual stresses, induced by the growth process. [64,65] Since FeCo is a magnetostrictive alloy, these stresses induce the appearance of a net magnetoelastic anisotropy contribution, K E , to the total magnetic anisotropy of the film. From the analysis of the magnetic hysteresis loops measured on FeCo ref with the field applied both in-plane (Figure 5a) and out-of-plane (Figure S8, Supporting Information), we estimate that K E ≈8 × 10 4 J m -3 , corresponding to a stress magnitude of ≈900 MPa (see Supporting Information Section S4 for more details).…”

Electronics and soft robotics demand the development of a new generation of hybrid materials featuring novel properties. Among these, remarkable mechani cal properties are required to sustain mechanical stresses, and electrical and magnetic properties are essential to design the devices' interface. In this study, a hybrid material is presented, consisting of a spider silk thread, providing mechanical robustness, coated with a layer of a magnetostrictive FeCo alloy, which ensures both electrical conductivity and stress-sensitive magnetic properties. The durability and the homogeneity of the composite are validated, as well as its ability to respond to magnetic and mechanical stimuli. Despite the coating, the soft nature of the silk and its mechanical performances are preserved. The magnetic study reveals that the magnetic behavior of the film is strongly affected by the silk thread-FeCo layer interaction, especially under mechanical stresses. Indeed, when the composite is subjected to tensile strain, the magnetic signal changes accordingly, indicating that the layer-silk interaction is maintained and can be exploited to reveal the tensional state of the sample even under severe cycles. Therefore, the presented hybrid material is a flexible fiber with properties that are suitable for magneto-electronics applications, e.g., magnetic actuators as well as strain/stress sensors.

“…Internal stress has always been considered as an important factor affecting the magnetic properties of ferromagnetic materials [1,2] . Low temperature stress relief annealing can partially remove the influence of quenching stress on the properties of soft magnetic alloy [3][4][5] but may do nothing about the stress originating between the surface layer and inner layer metals.…”

Rapidly quenched ribbons with a composition of Fe67Co18Si11B4 have been investigated. Surface leveling on the ribbon-free surface leads to the decline of the interior stress of Fe67Co18Si11B4 amorphous alloy, making a decrease of coercivity and a great improvement of static magnetic properties. Free surface leveling treatment can improve the AC magnetic properties of the Fe67Co18Si11B4 amorphous alloy. In high frequency region 106 Hz < f < 108 Hz, the quality factor Q > 3 can be achieved after surface leveling. Free surface leveling is an attractive method to achieve improvements in both static and high frequency magnetic properties.

Fe 50 Co 50 and Fe 70 Co 30 (50nm) thin films prepared onto the Silicon (001) substrate at room temperature using UHV DC Magnetron Sputtering (PVD) system. We prepared FeCofilms and characterized their Magnetic, Topographic, Morphology and Elemental analysis using VSM, AFM, FESEM, and EDAX technique respectively. VSM result confirmed both materials are good magnetic in nature and both their Coercivity nearly 200Oe but Fe 50 Co 50 has higher magnetization when compared to Fe 70 Co 30 film. From AFM results, the average roughness and root mean Square ofFe 50 Co 50 film value are double the times higher than Fe 70 Co 30 film. From FESEM result Morphology of the Fe 50 Co 50 film like a columnar structure and Fe 70 Co 30 as like columnar agglomeration structure. EDAX result revels high number of oxygen content present in Fe 70 Co 30 film than Fe 50 Co 50 film as well as no other impurities present in the film.
